Effects of microabrasion and bleaching on color and shear bond strength of simulated stained-remineralized caries lesions.

Purpose: This study investigated the effects of bleaching and microabrasion on the color and shear bond strength (SBS) of stained-remineralized caries-like lesions (s-RCLs).

Methods: Human enamel specimens were demineralized, stained (coffee/tea), then remineralized (2% NaF and artificial saliva [AS]) to create s-RCLs. Specimens were randomly divided into five groups (n = 18): G1, demineralized/AS; G2, s-RCLs/AS; G3, s-RCLs/at-home bleaching (15% carbamide peroxide [CP)], 6 h/d×7)/AS; G4, s-RCLs/microabrasion (6.

Efficacy of Visual Oral Health Reinforcement in Reducing Plaque Accumulation and Gingival Bleeding: A Pilot Randomized Controlled Trial.

Aim: To compare oral hygiene (OH) differences during verbal or video OH instructions with or without images displaying poor oral health consequences.

Materials And Methods: Twenty-one healthy females (18-30 years) were randomly and equally divided into three intervention OH instruction groups: (1) verbal, (2) video-based, (3) video-based with image displaying the consequences of poor OH. Gingival bleeding on probing (BOP), gingival bleeding index (BI), and plaque score (PS) were assessed at baseline and after 4 weeks.

Dental students' attitude towards propranolol non-medical use: A multi-institutional cross-sectional study in Riyadh, Saudi Arabia.

Introduction: The lives of college students are full of various stressors. Students seek a number of stress-relieving modalities as self-prescribed beta-blockers to improve their academic performance. The aim of this study was to assess the extent of beta-blockers (propranolol) usage amongst Saudi dental students and their attitude towards its use to enhance academic performance.
